Specification of Lettera Patent.

Application filed September 5, 1905. Be'ial No. 277',0B3.

T o altwhom it may concern.'

lic it known that I, EMMIT G. 'LATTAJ a citizen of the United States,residing at Syracuse, in the county ofiOnondaga and y State of New York,have invented a new und nset'nl Improvement in Ribbon Mechanisms. otwhich the following isa specification.

This invention relates to ribbon mechanisms for typewriting machines,and more j nirtirnlary to ribbon mechanisms for front l. .sti-iloltypewriters iii which the type bars have` two .sets of type and theplaten is norinaliy in printing relation with 011e set of typtI and isshifted to printing relation with t the other set of type. Soniefeatures ofthe im cntion, however, are-equally well adapted for machinesin which the type-bar segment is shifted insteadof the platen, and soineof the features are adapted for use with other than :front strikemachines.

The objects of the invention are to produce a poner-driven ribbontt'eedmeChaniSin of simple and desirable construction involving theminimum number of parts; to provide simple ineens for automaticallystopping the feed of the ribbon to prevent injury to the ribbon, and forgiving audiblefnotice when the ribbon is at the end of its run; toprovide :i ribbon feed reversing mechanism having an operating key orpart which isl always moved in t e saine direction to reverse the\ribbon regardless of the direction in which the ribbon is feeding; toprovide novel .means for guiding the ribbon and for vibrating the sameportion of the ribbon to and from the printing pointin two diierent po-`sitions of the platen, for holdi" the ribbon stationary in position forprinwg and permitting the ribbon to be moved to expose the printingpoint whenever desired, and for iolding the ribbon stationary out ofprinti ing position; and to throwing the ribbon fee the ribbon is heldont of printing relation.

Ant'ither object of the invention is to improve the ribbon mechanism,offtypewritin machines in the respects hereinafter specifie and setforth in the claims.

c toV swing upwardly is pivoted at its endsto the main frame at pomts ein rear of the platen. Theshift frame normally holds the platen inprinting relation with one set of type on the type frame normally holdsthe platen in printing relation with the other set of type by thefollowing mechanism: F represents a rock shaft journaled at its ends onthe main frame and having a toothed segment f meshing with a gear pinionf connected by a. crank or eccentric fz and rod f* with the frontportion of the shift frame. The rock shaft l has forwardly projectingrocker arms j which bear on the rear ends of shift levers r keys whichare located near the opposite sides of'the machine, are pivoted betweentheir ends conveniently on the transverse bar or support c", and extendforwardly to the key board. By depressing either of the shift keys G therocker arms f are lifted, theiieby'frocitilng 'the "shaft F which,through the toothed Seg lent, pinion crank and rod described lifts theyihift frame to place the platen in its u per printing position, whiciposition is in icated in Fig, 5. This platen shifting mechanism is fullydescribed in my application tiled June 14, 1905, Serial No. 265,217, andas therein eX- plained, ity is possible to shift the type-bar segmentinstead of the platen by a substantially similar mechanism. In so far assome of the features to be described are concerned, either the platen orthe segment could be shifted.

H represents space keys or levers pivoted between their ends on theframe bar 02 and carrying at their front ends the usual thumb bar le.These space keys or levers are, as usual, connected to the carriagecscapcment for producing the letter and word spacing, by mechanism`which forms no part of the present invention and is not shown in thedrawings.

The parts thus far mentioned are all more fully described in saidapplications and are thus brielly described herein to enable a propel'understanding of their relation and u. y J u coolneratlon with t hcrlbbon n'iechanlsnl.

may be of any ordinary form, are preferably splined on the upper ends ofupr1 ht spool` s aft K and removably retains on the Vshafts by nuts lcscrewed on the threaded esem' upper ends of the shafts. The nuts havecrank handles hy which they can be screwed on and ofi' of the spoolshafts and their threads are oppositel cranked nuts serve as liandlesfor turning th spools in the opposite directions necessary to wind theribbon thereon without unscrewing the nuts from the s )ool shafts. krepresents ribbon directin `evices, preferably in the form of hails Wlich embrace the spools, and have inbent ends which fit in `centraldcpreslsions im the spools and have holes through which 'the sioolshafts pass. The central parts of the ails are seated in the slots z'2in the spool seats, whereby the bails are held from turning, and areslotted vertically at k2 to receiye and guide the ribbon. The spoolshafts K are journaled in upper and lower bearings in which they areadapted to slide endwise, or vertically, the upper bearing be ingpreferably formed in the top of the 'frame and the lower bearings k3 ona transverse bracket la* secured by forwardly and downwardly extendingarms le to a front cross bar la of the frame. The bails move verticallywith the spool shafts and spools, which are shifted with the platen, andpre` vent the ribbon from wear and from twisting or folding where itpasses out of the spool seats.

L, Figs. 2 and 3, represents the usual spring driven drum (connected tothe car ringe by means not shown) for moving the carriage to the left.The spring druln is journaled on a shaft sup orted by a suitable bracketl or part of the rame.

t is a gear pinion journaled concentrically with the sprin drum andconnected thereto by means whic 1 cause the pinion Z to turn toxtheleftywith the drum but permit the drum to turn independently of thepinion in the op )osito direction when the carriage is set back-for anew line. l'nthe construction shown, thepinion 1s loosely mounted on thedrum shaft and is providedvwith integral ratchet teeth lgrengaged by aspringfprcssed pawl Z pivoted on the spring drum.

Z is 'a horizontal shaft havin a gear wheel ZF fixed to its rear end andmes ling withthe pinion Z. This shaft l* extends forwardly under theleft-hand endof the type-bar segment and at the left of the uprightauxiliary .type-bar levers c and is lournaled in suitable bearinvs,preferably int ietransverse bracket /n and1 in a bracket Z at the rearofthe frame. f i

lf is a bevel gear wheel which is splined or otherwise connected to t-hefront end of the shaft l? so as to turn With the shaft andslide thereon,and which is yieldingly held by a coil spring l surrounding the'sheftl*in mesh with a bevel gear wheel Z splined on a transverse horizontal-reversin'r shaft l1" which is'journaled to rotate an slide endwise inbearngeltyreerably formed the pitched, whereby tbs .r

sans?? ansverse bracket c. The bevel gear wheel is heldffrom endwisemovement between ,wo of the bearings for the reversing shaft. l Z aretwo bevel gear wheels which are fixed to the ends ofthe reversing shaft,are adapted to mesh res ectivel with bevel gear wheels l l spline on thel'o .er ends of the A spool shafts K, and are held against endwise`movement with said shafts by suitable means,

fiiubh as flanges on said wheels engaging in in the lower bearings for'the spool shafts. The reversing shaft is in gear with s only one spoolshaft at a time.

, With the reversin shaft l1 in the position shown in Figs. 2 an 3, thefeed mechanism 'ust described can s the ribbon to Wind ov'rly on theleft-h nd spool by the power Jof the carriage driving spring drum and,when it is desired to reverse the ribbon feed v so esto wind theribbonon the ri vht-hand spoolythe reversing shaft Z1 is simp y moved to theright fa-r enough to disengage the bevel ar at its left end from thegear on the le s ool shaft and cause the bevel gear at its rig t end tomesh with the gear on the right-hand s ool shaft. The bevel gear Z7 attliejjironten of the 'ribbon feed shaft being held,` in mesh with itscompanion gear l by ti spring l, can slip in the gear l when the on iscompletely unw'ound from either spool and the strain on the feed gearingis t ereby increased. As the wheel slips u toth 1t gives audible noticethat the ribbon feed should be reversed, and this notice is' repeatedwith each succeeding `tooth that slips andthe operator will soon noticeit. This arrangement of the gears' also prevents vfthe ribbon from beingtorn loose from the 40 to be thrown out of action, as hereinafter'described. It will be observed that by the described arrangement of thereversing shaft adjacent to the spool shafts, only one forwardlyfoxtending shaft is necessary, thereby saving t one shaft and one pairof gears over angry Y "rangement in which the transverse shaft is Llocated at the rear of the machine and conecte'd tothe spool shafts bytwo forwardly 'extending shafts. The reversing shaft is movedY toreverse the ribbon feed by means "having an operating part which `isalways moved in the same direction, regardless of which 'way theribbon'hi ppens to be feeding. fsf The ribbon feed reversing mechanismshown in the drawings is constructed as follows, see F 2, H, T and 8: Mrepresents' a slidable operating lever or push kev4 referably located4near the right side of t 1e key f3@ board and having an upturned frontend or a button mland M represents a late which is osclllated by saidpush key, e plate M is pivoted centrally at m on one of the arms ktpfthetransverse bracket c and has a stud rear of its pivot projecting up intoa groove in the hub of the bevel gear at the exhausted spool and enablesthe ribbon feed i right end of the reversing shaft Z1". The plate isprovided with an angle shaped slot mi in which engages a depending lugor part m* at the rear end of the push key, and has a. forwardlyprojecting portion provided Witha head m of V-erossseetion that is adated to snap downwardly over each side of t e supporting arm le toreleasably hold the plate in either of the inclined positions shown in Fi s. 2 and 7. The push key is mounted to s ide and swing laterally 011the 'lipporting armk?, as by a screw or pivot lm." asing through anelongated slot m in the push ke and is normally held in the centralforwar position and returned to such position after movement by asuitable spring m located in a slot in the supporti-ng arm and connectedto the pivot and the push key, When the ribbon is being wound on thelefthand spool the reversing plate M will bein the Osition shownin Fig.2, with the depending ug at the rear end of the pu;h key engaging in theleft-hand inclined portion of the slot` in the reversing plate M. Toreverse the feed the push key in forced rearwardly until its dependingrear end, which is led to the left by theslot in the reversingr plate,l

strikes the end of said slot and oseillfat said plate on its pivot tothe position shown in Fig. f7, in which position the plate is held bythe engagement of its V-shaped head with the left side of the supportingarm Ict.4 The movement of the plate moves the reversing shaft Z1" to theright, throwing it ont of gear with the left-hand spool shaft and intogear with the rightshand spool shaft. The return of the push key to thenormal forward ,position by its s )ring m, will throw its depending rearen into the inclined right end of the s lot in the reversing plate, sothatfthe nextttime the push key 1s oreed rearwardly it wi l oscillatethe plate in the oppositeidirectioh and move the reversing shaft againshaft. This reversing mechanism is located where it can be reachedwithout removing the hand from the key board and it is especiallydesirable for the reason that the movement of the sameart in one andnthe same direction always e ects the reversal of the ribbon feedregardlessof which way the ribbon is feeding. It is positive in itsaction and relieves the operator from the necessity of looking to seewhich ribbon spool requires to be thrown out of action, thus savingtime. 'Ihe ribbon feed and'rcversing mechanism are not necessarilylimited in application to a front strike machine of the kindillustrated. ,Y The ribbon is led', as usual, from one spool to theother through a guide or support located centrally in front of thefplaten, byV

` vers, while the front Ing point. The guide N, Figs. 1 to 6, ispreferabl formed of a single piece of sheet meta ihaving its lower endfolded around and riveted to a vibrator rod n which is arrangedsubstantially upright between the central type bars and is pivoted atlts ends to upper and lower vibrating supports n nl The upper supportpreferably consists of two horizontal diverging arms pivoted at theirrear ends to the top of the frame, While the lower support consists of arigid ar'm pro jecting forwardly from a rock shaft a3 having endbearings in the ro'cker arms f of the ptaten shifting mechanism. Therock shaft u has two rigid arms a* near its ends which projectrearwardly beneath the rock shaft l and are pivoted tothe uptnrned endsof a pendent ball n", the cross-bar of which passes beneath the keylevers and forms a universal bar. The rock shaftn"l and its forwardlyand rearwardly projecting arms constit|1teinetfect a vibrator lever, and the rocker a rmsl f adm-d a movable fulcrum support` for this lever.As the key levers a re of four different lengths. they are provided overthe universal bar with depending lugs u." of four diiferent lengths. tbelugs of the longest le vers resting on tbe universal bar and the otherlugsl being diil'erently spaced from the universal bar according to thelengths of their respective levers so that each lever will depress theuniversal bar the san'iedistance. The ribbon vibrator is normally helddown, with tbe ribbon below the printing point, as shown in Fig. 1, by asuitable spring nf connecting the front arm of the vibrator lever with asuitable part of the machine. such as a brackety n projecting from thecrossbar n2 of the frame. The upper end of the spring is adapted to besecured to the vibrator lever nearer to or farther from its fulcrum toregulate the action of the spring. lhen a key lever is depressed theuniversal bar-will be lowered. thereby rockingr the vibrator leverandlifting the ribbon vibrator to locate the upper portion of the ribbonover the printing point in time for the type to strike the ribbon. lVitbthe return of the key levers the spriingl n? restores the universal arand vibrator to normal position. then the platen is shifted by means ofeither of the shift keys G acting through one of the rocker arms j, therock shaft fr; or fulerum of the vibrator lever, is raised, as shown inig. enough to lift the vibrator and rib` bon an equal distance with theplaten. This lifting of the vibrator is due to the universal bar andrear end of the vibrator; lever being held from upward movement by `thekey leend of the vibrator lever swings upwardly with its supportingrocker arms f. The ribbon is thus gh en a new normal position just under(the prit ting point on the shifted platen, and this position 1t assumesautomatically eajch time the platen the platen The ribbon 'ust i isshifted and retains so long as is held in the shifted position. vibratesto and from this new position J as from its lower normal position'. l`heshifting of the laten does not alter its relation to the rib on.

The type bars, as before stated, have un accelerating motion inapproaching the printing ont, but it is desirable for the ribbonvilliator to have a uniform motion, and this is accomplished by theuniversal bar and connections described. Preferably i this universal baris employed only for operating the vibrator and is not connected i tothe carriage esca pement, the latter being operated b van independentuniversal bar shown in Fig. l. Where the separate universal bar for thevibrator is employed its retraeting spring can be made so light thatwhen the machine is operated at considerable speed it will not return te universal bar as rapidly as the key levers are returned, thus leavingthe vibrator elevated between the impressions during the time a Word isbeing printed and ,permittin the vibrator to expose the writing when tyeiinger keys are at resty or when the speedof themachine is lessened.This action of the vibrator can be secured by adjusting the upper end ofthe retracting spring n near to the r fulcrnm of the vibrator lever,thereby giving-the effect of a lighter spring. By the describedconstruction of the ribbon vibrating mechanism entirely independent ofthe I shift frame andvearriage, these parts may be removed and replacedwithout disturbing any party of the ribbon mechanism. The independentuniversal bar for actuating the escapement is indicated at nl", Fig. 1.

ar is segmental in shape and may be movably sup )orted by swinging linksn over the typear segment in by the typc-bars C when they approach theplaten. The rear supporting links are secured to a rock shaft connectedby a rock arm uw to a rod um' which is connect-ed to the dog of thecarriage escapement nl". The ribbon spools are also lifted when theplaten and the vibrator are shifted, as above exposition to be struck ii i deflecting ofthe ribbon with the consequent curling of its edges.This isuccom lished l bythe rocker arms f3, the upturned) front i endsof which, when raised by the depression of either shift keyG, strikethei'ower ends of the' spool shafts and lift them vertically, as shownin Fig. 5. their shafts return to normalposition by gravity when theplaten is permitted to return to its normal lower position.

Means are provided for holding the vibrator stationary. either in anelevated pov sition with the ribbon in printil) relation, or inadepressedv position with below the printing point. The means shownplained, thereby avoiding the twisting ori ribbon The spools and Aresentthe front an inthe drawings for doing this are oonstructof one of thespace keys H. The ribbon ed as follows, see Fiigs. 1 4 and 6i' OOreprear arms of a jointed key or lever, the two arms being pivotedtogether and to the transverse bracket le* at A spring p coiledabout'the pivot p and earing a met the two arms of the key or leverpermits the loyer to be flexed me way while overlapping parte of thearms 'cause the two arms to act use rigid one-piece lever the other way.he lever is normallyI held in the posit'romshow'n in Fig. 1 by a spring11S-connecting` `afdepending leg p on the front arm of the lever'withthe cross-berk of the frame. The lever is" rovided at its front end with'a key p* pre erably-pivoted thereto and having a depending' curvedshank p that passes downwardly through a slotted plate p0 sec'ured onthe erossbar k of vthe frame. The key shank is provided near its upperend with a shoulder p1 adapted to be enga lred under a coperating'rhookor part ps of t e slotted plate p by pressing rearwardly. on the keywhen depressed for looking the key in its lower position, and thenotched lower end of the key shank 1s adapted torbe'en aged over anotherhook or part 71" on the s otted plate p by liftin the key and pressingit forwardly to look tie key in a raised position. The rear portion ofthel ribbon shift lever O O passes between the central auxiliary tye-bar levers and ends in a cross head 111 oeeted inl front of thevibrator rod beneatha forwardly pnojecting lng pl thereon. The spring pis of greater strength than the retracting spring yn? for the vlbrator,so that when the front end of ribbon shift lever4 is depressed to thelimit of its movement the rear end of the lever acting on the lng of theVibrator raises the latter sons to locate the lower part of theIvil'n'ated` while in ribbon `in printing position. 15),'.loeking theribbon shift lever in its depressed position, as explained ,and as shownin Fig. 6, the lower part of the ribbon is retained over the printing'point,` and as the raising of the vibrator n lowers the nni\'ersal baront of reach of the key levers, the ribbon is not Y the -elevatediosition. Thisl adjustment of the parts enables the use of the machinewith a non-vibrating ribbon, which is preferred, by some operators, andit also makes it possible to write with two colors by using a ribbonhaving different colored ink on its upper and lower` portions, asindicated at I, Itig. 12. v

By the simple depression 'of the ribbon shift leverthe ribbon can bechanged for au single impression of different color, and by locking `thelever 'down the lower color can 1 `which projette rearwardly from theshaft n of the vibratorlever and strikes the rear end .rif

movement yof the part of the ribbon 1s maintained in printing shiftlever, is flexed somewhat in, thus raisring the vibrator andconsequently it the platen is shiftedY ,and the vibrator lever raised asbefore explained, when the ribbon is in this raised position, the spring79 connecting the two arms of the ribbon shift lever will assert itselfand raise the ribbon a distance corresponding with the upward laten.Thus the lower relation with the 'platen Whether the latter is shiftedfrom its normal position or not. The ribbon can be lowered from itsraised position just described to expose the printlng point wheneverdesired, by de ressing the space key H, which de resses t e front end ofthe vibrator lever wardly on the ariii Q thereof. The spring p' of theribbon shift must be compressed to,

do this,

R represents a rod which is pivoted at its rear end to the universal barand extends forwardly between the auxiliary type-bar levers, and isslidably supported at its front end as by a pin r on the plate p passingthrough a\ slot in the rod. A spring r' connecting the rod and thebracket n normally y pressing upi forces the rod R rearwardly and holdsthe universal barbeneath the operating lu on the finger keys, as shownin Fig. 1. hen it is desired to hold the ribbondown below the printinpoint, as when the machine is tobe used or stencil work, the ribbonshift 'lever O (Y is raised above its normal position and locked asbefore explainedgee Fig. LJ. When thus raised' the depending leg 'p2 ofthe lever strikes a shoulder 1' on the frontend oi' the rod It andpushes the rod forwardly, thereby n'itlnlran'ing the nniversal bar frombeneath the operating1 ln s on the key-levers, and permitting thevirator to fall and carry the ribbon below the rinting point far enoughto be cleared by tie type. In the forwardposilion of the nniversal'barit is not actuated by the key-levers and the ribbon remains stationarybelow thprinting point. 'lhc vibrator is p revcnte falling too far byvthe engagement "of the rear arms of the vibrator lever against theplaten-shifting rock shaft F. Then theribbon is held down ont of use, asjust explained, it is desirable to throw the ribbon feed mechanism ontof action lo save the nribbon and feed mechanism froln wear when forthis purpose, see Figs. 3 and 1l: S represents a lever pivoted centrallyto thelower from i side of the transverse bracket k, with its inner endin front of a depending lu s on the rear arm O' of then'ibbon s hf Theouter end of the lever S is'curved upf wardly in rear ofthe bracket la*and termi" nates in front of the sliding bevel gear Z7 on the ribbonfeed shaft Z.A Then the ribbon shifting lever is raised to lower theribbon for stencil Work,A the lug a thereofpushes the inner endI of thelever S forwardly, causing theoiiter en' of the lever to slide the bevelgear ZT out of mesh with its companion gear and throw the ribbon feedout of action. When it is desired to a ain use the ribbon, the key ofthe lever O' is disengaged from its holding hook on the plate p. The sring r will then draw the rod R rearwar y, returning the universal barto its normal position and causin its shoulder r2 to strike the leg 712of the ri bon shifting lever O O' and returiisaid lever to its normalposition. The s ring r' is enabled to do this notwithstan ing theopposition of the spi'in pon account of being stronger than sai springp3. The lug s isy thus withdrawn from the lever S and the bevel gear ZTis again thrown into mesh with its companion gear by its spring, therebyrestoring the ribbon feed.

The universal bar a5 couldebe utilized t/o operate the carriageescapement, but this is not so desirable, as in that case the rod R forthrowing the universal bar out of action for stencil cutting would haveto be omitted and the ribbon could not be locked in its raised positionwith the lower part over the ing less ower; the ribbon feed gear canslip to avoi injury to the ribbon; audible notice is given Vwhen theribbon should be reversed; sina'ple means are provided for securing theribbon spools 'to their shafts and turning them manuallyand forpreventing the ribbon from folding as it passes to the spools; theribbon feed can be reversed by t thereby saving time and avoidingconfusion; the ribbon is vibrated with uniform motion; the ribbon ismaintained in the same relation to the platen in the normal andshifted"positions thereof; theribbon' can be held stationary over theprinting point, and lowered to expose the Writing and again returned bymeans of the space key; a composite ribbon can be used; and the ribboncan be lowered ont of the way and its feed thrown out of action forstencil work without disconnecting the ribbon or any part of themachine.
